- 'Thisinvention relates to cementing machines, the type of apparatus herein described being especially adapted for operating upon the channels of the insoles of shoes fi preparatory to layingthe channel-flaps.

'Qbjects of theinvention are to provide an efficient ma'chme of this character which will be readilyadaptable to coatmg areas of differei'it widths'and to applyii'l'g'coatings of different thicknesses, and whichwill avoid dripping and waste of cement. A feature of the invention attainment of these objects involves means for simultaneously varying the dimensions of a casing in which the brushor' other applying member rotates, andthceifective co operation between such applying member and its scraper or member which controls the delivery of cement to the work; Such a com struction allowskwith minimum effort on the part of the operator, the mounting upon the machine of applying members varying in widths, with'an automatically attained cor responding variation in the scraper for such applying members; In the illustrated emv bodiment of the invention, the applying member rotates within a casing, the side walls of which are relatively movable to cause this. casing toconform to the brush, while the-scraper is movable with oneof thesewalls and is correspondingly shifted across the periphery of the applying member. Preferably, the applying member. is'movable lon- 'gitudinally of the shaft which rotates it, and is forced by the movement of one wall into co-operation with the companion wall, so that tight joints are furnishe d'to prevent the leak ire of cement between these elements. The casing as a whole is shown as movable transve .ly of the axis of the applying memv vthe scraper toward and from the'periphery of the applying'member. to control the cement laid thereby upon the WOZk.

The escape of some of the cement at the sideof theapplving member is unavoidable,

' and this cement tends to, gather upon the movable support of the member, as the hub "through which it is rotated. In thisconnectioin a feature of the invention consistsin leading to the directing the cement accumulated upon the ing member, which means is'utili'zed to com pletely shut on" such flow upon the separation of the receptacle from the frame. Operators sometimes forget to effect this closure, and much. cement is wasted and'surrounding obsoiled. A further feature of the inven tion'has todo withmeans' forpreve'nting the removal of the receptacle in predetermined positions of the controlling means. Herein are shown a valve co-operating with a discharn'e-opening from the receptacle, and means. which may be carried by the machine frame, for preventing the removal of the re- ,ceptacle unless the valve is closed.

The accompanying drawing illustrates a particnlarformof the invention, I

'At 10 appears a standard having, secured upon'its upper extremity, a casing 12 for the actuating elements of the apparatus, power being furnished thereto by a motor 14 bolted upon one side of the casing. The motorshaft 16 is connected through reducinggearing 18 to a shaft 20 journaled in the wall of the casing'12opposite themotor-shaft. Car- .ried'bythe shaft20 is an'app'lying member,

preferably furnished by a brush 22 rotatably connected to the shaft, while longitudinally movable on and readily separable from it, by a pin 24 projecting from said shaft and en tering a longitudinal slot 26 in the hub 27 of the brush. gAssociated with this'applying member is ayieldable channel-flap-guide and flap-lifting finger 28, generally corresponding in character to that of United States Pat-- ent No.'1,004,705, Stanbon, Oct. 3, 1911, save that in the present device, themeans for sup, plying liquid to the flap is omitted. This guide is carried upon a shaft 30 rotatablein the casing 12above the shafts 16 and 20, and

vibrated through an arm 32 fixed upon it and having at its lower extremity a yokey34tembracing a cam 36'fast upon. the motorshaft To supply thebrush with cement, there is mountedupon the top of the casing 12 atank or receptacle 38 having a cover lOforming a tight closure, and, at the bottom, downs wardly inclined walls 42 Fig. 2) converging to'an opening 44 (Fig. 5); This opening communicates with adelivery-opening 46 formed'above" the brushin a horizontal arm 48; formed upon the upper portion ofthe casing 12'. Thetank 38 is made readily removable, so that it may be taken from the ma;

chine for storage atnight,to lessen the firerisk, and is fixed in place upon the casing12 by opposite pins 50, 50. In a recess 52 (Fig.

6), located at the under side ofthe tank 38 beneath the opening A is a"val vehaving a plunger 54: movable back and fo'rth across the 1 opening, so' that such plunger may completely close. it',for may vary the area to controlrthe amount of cement discharged. The end 56 of theplunger isshown as inclined upwardly 'andrearwardlvlconsidering the direction of movement for closure, this inclination reducing'the resistance to the forward travel of :the plunger. Connected at 58 to thevalve plunger is'a lever 60-(Fig. 15'), fulcrumed at 62 upon thetank. The rear extremityofthis lever, beyond the fulcrum has threaded through-it a stop-screw 645, which contacts with a surface upon the tank. By adjusting this screw, the amount of closure of the open ing 44 may be determined toregulatethe flow ofcement, or upon'asufficientbacking-0E of V the screw, the valvemaybe closed completea 11y; 'Fixtending laterallyfrom the horizontal:

"arm' 4 8 nearthe bottom of the tank, beneath andthen vertically'past and over the upper face of the lever 60, is a retaining member,

furnished by a hook 66. The extension of this hook-portion over the lever is such that when the valve is closed, the lever is free from engagement withthe hook, so that the tank I may be taken from the machine. If, how- .7

ever, the valve-plunger is so positioned that the outlet of the tank is open, the lever comes beneath thehook, rendering it impossible to raise the tank from the frame, and thus warn ing the operator of the condition of the valve.

Holding the delivered. cement in temporary association with the upper peripheral portion 'ofthe brush is a casing C. This casing is preferably carried by a slide 68' (Fig. 2) .movable in ways 70 in the arm 48. The

casing includes a wall 72 depending 'from the of the brush, to-forin part of the casing C and make a contracted. throat through. which L the. cement is carriedifdownward-ly tothe work. The scraper 76 isadjustably held in place upon the slide 68 and hence upon the wall 72, withits inner face pressed against the edge'fll of -tlie'wall'72, by a screw 78 passing through:a horizontal slot in the use scraper and being threaded into theslide.

This connecti'onpermits the scraper to be adjusted transversely of the brush, to correspond to its width, thus varying its effective co-operation with the-brush. f Carried by and integral with the'scraper is awall 80 (Fig. 4), furnishing the opposite side of the casing G from'the wall'72, and having'its inner face similarly related to the opposite side of the brush. Upon this' wall 80 is ,a depending flange 82 (Fig. 2),"whi'c'h' contactswith thebody of the brush. WVhen the scraper is adjusted across the applyingv surface, by virtue of the slotted connection to the portion? 1'' of. the slide, the wall 80-is correspondinglyinoved towardthe wall 72 to varythe width of the casing C, the flange 82 pushing'against the brush. so that the inner SlClGfOf the brush is brought into close conwhile at tact with the. face of the wall 2, the same time the outer wall 80 ismaintained against theouterside of the-brush; In' this way, by a single adjustment by the operator,

the casing 'is caused to erlra'ctly fit the brush laterally, with tight joints at its sides, and 7 At the'upper' portion of thejcasing, a surface 84 (Fig. A) at thetop of the scraper? 6 and the scraper is maderelfective over the particu Qlar peripheral width'of the'brush employed.

so thatthere can be no leakage at this point while movement oft-he casing C isoccurrin'g by the shifting of the slide 68. To effect this movement of theslide, there isprovided a bracket 86' projecting from the arm 48 on the casing 12 and having turning but held against endwise.movement in it,'a horizontal screw :88 engaginga threaded opening 90 in the end of the 'slide.-- VVhenthis screw is turned, the slide is moved to alter the-space between thelower edge'of the scraper and the periphery of the brush (Fig. 6.). This coiitrols the amount of cementremovedfrom the casing, to which it has been delivered hroi'igh the openingsxa land a6, and consequ'entlyTvaries the thickness of the coating applied to thework A lock-'nut92 may be provided to retain the screw 88, in its adthe work orthe' floor, it inste'ad remaining up'onthe bristles; to he applied to the work, or carried back 'toth'e casing at the upgoing side of the brush. 1 r

In spite of the effectiveness of the closure at tlrefsides of thee'asi-ng, soihe cement will escape, and, gathering" upon thehub,27,-v. ill tend to drip. from the machine. To prevent V this,-- a fiired' blade 94; (Fig.5) ismoi'mt'ed at 9.6 upon the'framefit having an edge 98 curved to conform to the brush huh and ly- This blade, at its ward the brush in the direction of rotation.

from which it is'utilizecL-f i "The illustrated apparatus is employed in the manner customary with channel-cementmg machine-aims shoes operated upon being placed with the under side of the open flap 112 uponthe top of the finger 28, with the upper side, or what, in the finished s oe, is the interiorof the flap", in eomaem h the brush 22 as in FigQ? The operator selects a brush of such width that it will apply the *cemeiit tr'om its periphery'over the exposed ctac'eo'f the fiapand over the wall oithe sole 'with wliich' this'race is to contact when p Atterapplyin'g 'tl i brush to the machine,- it is only necessary for the operator to press'the wall-80 and scraper 7 6 inwardly, so that'ths depending tiange 82 forces the brush against the opposit wall 72. Then, upon securing the parts in place by the screw 78, the casing and scraper will have been exactly adjusted to the transverse dimensions of the brush. The valve 54: is opened sutliciently to keep the casing constantly supplied with cement from the receptable 38, without overflowing rearward-ly, and the slide 68 movedby the s'creWBS to give the proper width of throat at the lower edge or" the scraper to insure the desired thickness of cement upon the periphery of the brush. The shoe is advanced by the operator over the flap lifting finger 28, which guides the work and holds the flap inc0ntact with the brush, at the same time smoothing out its irre 'ularities. For operating upon soles wit iout channels, the finger 28 may beremoved, and a-work support 100 (Figs. land 2) brought into use as in Fig. 8.

Thiswork support has a rounded upper face (not shown) and is supported by a screw 102, passing through a slot 104: in a 'proj e'etion from the casing 12. It has upon outer or'upper face a gagesurface 106, with which the edge of the sole to be operatedupon may contact. WVhen the finger2S is in use, the work support 100 hangs vertically from its supporting screw as in Fig. 2; but when this support lOO-is to be employed, it is raised to lies a horizontal position, and there fastened its screw, the slot 104 permitting the gage surface 106 to be correctlylo'cated "to determine the area to be cemented by the brush.
